when I try to play a 360 game on my Xbox One it tells me that my profile can't connect to...

I just removed my profile from my XBOX one account and then added it back in with no problem. When I go to play a 360 game and try to download my profile, it keeps telling me that the password is not correct. Please advise.

I can't, it says that it's not connected to the internet. My xbox one is connected to the internet but when I try to play a 360 game on the xbox one it says that it can't connect to the internet.

I am also having trouble connecting to Xbox Live while playing a Xbox 360 game via Backwards Compatibly. I'm trying to get Halo 3 working. When I launch the game from my games and apps the game will load. It gets to the Halo 3 title screen. I press the view
button and menu button on my controller to open up the Xbox 360 dashboard menu. It tells me I can connect to Xbox Live. I do, then it tells me there is an error connecting to Xbox Live and gives me an error code. The error code is 8015190E. Selecting the option
to go to settings just takes me to the Xbox One network settings, a dead end basically.

I read online that some users got it to work by deleting their Xbox 360 profile from the emulator guide by selecting Manage Storage. Well, I was able to delete my profile, but now I am not able to re-download it by selecting Download Profile from the guide.
It keeps telling me my Xbox can not connect to Xbox Live.

I am able to connect to Xbox Live from my Xbox One and I'm able to browse the store and play Xbox One games like normal. However, everytime I want to play an Xbox 360 game on my Xbox One I am not signed in and I have no profile stored

What the heck happened?!

Same thing just happened to me. Can't connect to Xbox Live on my Xbox One but funnily enough can on my Xbox 360. Keeps telling me to check my network but when I do it says it's working fine. Won't let me play any of the downloaded games.

I understand what your saying about Diablo III but the problem isn't the game. everytime I try to sign into my profile the xbox can't connect to xbox live. I delete my profile and it connects. I redownload my profile again when it trys to connect I get an
error message 80151911. When I test the connection everything connects but it gives me a matchmaking error. The error not only applies to Dablo III but also Ghost. As a matter of fact even if I try connecting to Netflix it gives me an error message 80151911.
Also one more thing regardless of the game im playing. I restored my xbox 360 to factory reset, why isn't allowing me to connect with xbox live with my profile? The console connects to xbox live without a profile. I hope this can clerify better the situation.
